Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a comb type reciprocating electric shaver, more specifically,
This is a blade-type reciprocating electric razor that uses a comb-like fixed blade and a movable blade to shave the face, such as armpit hair and eyebrows, and its main purpose is to shave the mouth of the bundle tube that can be grasped by hand. By rotating the blade block that is inclined with respect to the direction around its axis, the cutting edges of the fixed blade and movable blade exposed on the blade block can be moved to appropriate positions depending on the area of use such as the armpit or eyebrows. To provide a comb-type reciprocating electric razor that allows one to easily shave armpit hair and eyebrows in a comfortable posture.

The present invention will be described in detail below based on embodiments shown in the figures.

The comb type reciprocating electric shaver according to the present invention has a motor 1
a slender bundle tube A with a built-in blade; a connecting tube B protruding from the upper end of the bundle tube A along an axis inclined with respect to the mouth axis direction of the bundle tube A; a fixed blade 3 and a top of the fixed blade 3; A slender blade block C, which is equipped with a movable blade 4 that slides back and forth, and whose lower end is fitted into the connecting cylinder B and is coaxially connected to the connecting cylinder B.
and a drive rod 2 that protrudes from the connecting cylinder B and is reciprocated by a motor 1 along the axial direction of the connecting cylinder B.
The blade edges of the fixed blade 3 and the movable blade 4 protrude from the edges in the width direction of the blade block C, which are perpendicular to the axial direction of the blade block C.
is rotatably connected to the connecting cylinder B around the mouth axis of the connecting cylinder B, and the upper end of the driving rod 2 is connected to the bearing 5 at the lower end of the movable blade 4 around an axis along the longitudinal direction of the driving rod. It is characterized in that the movable blade 4 is rotatably connected and reciprocated along the longitudinal direction of the blade block C on the fixed blade 3 by the reciprocating movement of the drive rod 2 by the motor 1, In this embodiment, the blade edges formed at both ends of the fixed blade 3 and the movable blade 4 are exposed at both ends in the width direction of the blade block C, one blade edge becomes a long blade edge for shaving armpit hair, and the other blade edge forms a long blade edge for shaving eyebrows. An example of a short blade edge for shaving is shown.

The bundle tube A is formed into an elongated tube shape with both ends open, and a motor 1 and a battery 10 are housed coaxially therein, and the lower end is closed with a battery cap 11.

The connecting cylinder B has a round part 12 protruding from the upper end and a bulging lower part, and the leg pieces 13, 13 extending toward the lower end side are fitted into the upper end opening of the bundle cylinder A, and each leg piece 13 is The provided locking protrusion 14 is fitted into the recess 15 on the inner surface of the bundle tube A, and the connecting tube B is fixed to the bundle tube A with its mouth axis direction tilted by 5 to 30 degrees with respect to the mouth axis direction of the bundle tube 1. .

A pin shaft 16 is installed between the leg pieces 13 and 13 in a direction perpendicular to the four axes of the bundle tube A.
An eccentric cam 17 is rotatably attached to 6.

The output shaft 18 of the motor 1 is connected to one end of the eccentric cam 17 in the axial direction.
A gear 20 is formed which meshes with a pinion 19 fixed to the motor 1, and as the motor 1 rotates, the eccentric cam 17 rotates eccentrically around the pin shaft 16, and a bearing ring 21 at the lower end is rotatably covered with the outer periphery of the eccentric cam 17. The fitted drive rod 2 is made to reciprocate along the axial direction of the connecting cylinder B.

On the other hand, the blade block C has an elongated flat blade holder 24 at its upper end, and a fitting cylinder 25 which fits into the round part 12 of the connecting cylinder B at its lower end.
and a blade holder 2 of the blade holder 26.
4, a fixed blade 3 and a movable blade 4 are attached to the blade base 27, and a push-up spring 28 and a movable blade 4 are attached to the inner surface of the blade base 27. fixed blade through 3
is attached with pin 29.

That is, the boss 30 protruding from the inner surface of the blade base 27 fits into the through hole 31 of the push-up spring 28, the elongated hole 32 of the movable blade 4, and the mounting hole 33 of the fixed blade 3, and the pin 29 fits into the top of the post 30.
The fixed blade 3 is fixed on the blade base 27, and the movable blade 4 can slide on the fixed blade 3 at the ends of the vertical range of the elongated hole 32.

A bearing 5 is provided at the lower end of the movable blade 4 and has a substantially U-shaped longitudinal section and a semicircular engagement groove 6 inside. The movable blade 4 is rotatably connected to the locking groove 6, and the movable blade 4 is provided in the longitudinal direction and reciprocated by the drive rod 2.
It can be rotated freely around the axis.

Here, a slit 35 that communicates with the inside is formed along the circumferential direction on the outer circumferential surface of the fitting cylinder 25 at the lower part of the blade holder 24, leaving a part of the circumferential direction. A flange 36 is formed around the entire circumference, and as shown in FIG. By contacting the outer periphery at a portion below the flange 36, the blade block C is prevented from coming off from the connecting cylinder B, and the blade block C can freely rotate around its longitudinal axis.

Furthermore, the blade block C can be stopped at any rotation angle by the frictional force acting between the ring 37 and the round part 12, and is suitable for shaving armpits and eyebrows, as shown in FIGS. At the same time, rotate the blade block C 180 degrees,
Alternatively, by rotating the blade between these two positions, the edge of the blade is set at an easy-to-handle position depending on the location of use.

In the figure, 40 is a power switch, and 41 is a protective cap attached to the blade block C.

As described above, the present invention connects the blade block coaxially to the connecting tube that projects obliquely with respect to the four axes of the bundle tube, and allows the blade block to freely rotate around its longitudinal axis. Therefore, the edge edges of the fixed blade and movable blade exposed on the widthwise edge of the blade block can be adjusted to appropriate positions depending on the area to be used for shaving, making it possible to maintain a comfortable posture without having to change your grip on the bundle tube. It has the advantage of being easy to use, allowing you to shave your armpits and eyebrows.
